CARIBOU, Maine — Shawn Martin is a perfect two-for-two. And he’s looking to make it three-for-three.

Martin is the defending two-time winner of the Last Chance Motorsports 150 at Caribou’s Spud Speedway and the Frenchville native will return home for the fourth annual Late Model race at 1 p.m. Sunday.

He didn’t run the first 150.

Martin, who now lives in Turner, is the newly-crowned Late Model champion at Oxford Plains Speedway, and said this is one of the highlights of his racing season.

“Any time I get home it’s a fun weekend,” said Martin. “I’m going to make it a big weekend. I’m going to see my family and friends and go to my parents’ camp.

“Hopefully, things will go my way on Sunday,” said Martin.

The winner’s share will be $2,000 out of the $10,000 purse but there will also be bonus money including money for leading a sponsored lap.

Jere Humphrey of Last Chance Motorsports will be the promoter and said the bonus money includes $100 for winning the pole, $100 for leading at the halfway mark and $100 for finishing 15th.

The last-place car is guaranteed $200.

Humphrey said he had 24 cars pre-registered as of Thursday including drivers from all of Maine’s six tracks.

Martin said he will “play it by ear” on race day.

“You don’t want to use your stuff up too early,” he said. “Hopefully, we’ll make the right adjustments on the car during the day.”

Fort Kent’s Austin Theriault, the winner of the Maine Young Guns competition, which has earned him a ride in a K&N Pro Series East race at New Hampshire Motor Speedway later this month, will be another favorite. Theriault, a development driver for Brad Keselowski Racing in the Super Late Models, is currently running third in the American-Canadian Tour.

Speedway 95 regulars Mike Hopkins of Hermon and Andy Saunders of Ellsworth will also be threats, and Liberty’s Josh St. Clair is another one.

Connor Thibeau of Fort Fairfield is the Late Model points champ at Spud Speedway and he hopes to be in the thick of things.

“I’m going to approach it like any other race, I suppose,” said the 18-year-old Thibeau. “I think I’ll have one of the faster cars there.

“You’ve got to hang in there and keep your car together so that you can [make a run] at the end,” said Thibeau, who finished third in last year’s race.

There will be extended lap races in four other classes and higher payouts.

The normal payout for a Late Model winner is $750 and there will a Fast Four (four-cylinder) race that will pay the winner $642 instead of the usual $200.
